Class ResourceKey

public final class ResourceKey extends Object implements Serializable

The key is an unique identifier for the resource. Most of the time, this may be an URL, but other (especially database based) schemas are possible.

A resource key must provide an 'equals' implementation. ResourceKeys should be implemented as immutable classes, so that they can be safely stored in collections or on external storages (like caches).
